WATER-HEATING DEVICE.

Specification of Letters Patent.

Patented Sept. 2, 1913.

Application filed August 29, 1912. Serial No. 717,781.

To a 'IP/MJWL it may concern Be it known that I, Vio'ion Josnrn TOUCHARD, a citizen of the French Republic, and resident at Rue Beaugrenelle 1+1, Paris, France, have invented certain new and useful Improvements in Water-Heating Devices, of which the following is a specification.

My present invention relates to water heating devices capable of quickly heating water particularly for use in households or medicinal purposes. Devices of this kind heretofore known are objectionable in that they require special arrangements and besides are not permanentl ready for use. These objections are comp etely removed by my present invention, which has for its object to provide a device for quickly heating water for use in households or medicinal purposes, in which water is heated within a manifold coil-tube by means of a burner.

One feature of the invention consists in using a coil tube, which is coiled in horizontal and vertical directions and arranged within a comparatively small removable casing, adapted to be directly fitted upon any existing burner.

The purpose of the invention is to produce hot water immediately after the burner is ignited, which is very important for medicinal or domestic purposes.

My invention will be readily understood from the following description taken in connection with the accompanying drawings, wherein I have illustrated several constructions of my invention.

In these drawings :Figure 1. shows a longitudinal section, Fig. 2. is a cross-section on line AB of F ig. 1; Fig. 3. shows another form of construction, and Figs. 1 to 7 show different coil-tubes.

Secured to the gas-cock 2 is a Bunsen burner 1, provided with a controlling device 3, whereby the admission of air may be controlled. Arranged at the upper end of the burner provided with a sieve, is a sievelike hood 4, whereby the flame is distributed upon the whole area of crosssection of the casing. The sieve 4 serves merely to prevent the flame from flashing back into the burner. The tube of the burner is moreover provided with an annular shoulder 5, serving to support the bottom 6 of the easing 8, whereby the latter is held in position. The bottom 6 of the casing 8 is provided at its outer periphery with a flange 7, through which extend the fastenin bolts 12 of the cover 10, having also a perlpheral flange 11. The fastening bolts 12 extend preferably through tubes 13, which however ma be re placed by flanges or shoulders provided on said bolts. Screw-nuts 14 are provided to secure the bolts 12 in osition. The casing is provided with openlngs 9 for the admission of suflicient quantities of combustion air. Arranged within the casing is coiled water-heating tube 15, which forms a horizontal coil as shown in Fig. 1. Water is admitted into the same at 16 and discharged from the same at 17, and to this end the inlet of the coil is provided with a screwthreaded extension 18, while the outlet is provided with a similar extension 19. To these extensions 18 and 19 are connected admission and discharge-pipes 20 and 21 respectively by means of suitable couplin nuts. As some water may be accumulate within the casing owing to the condensations produced within the latter, I have provided said casing with a dischargeipe 22, whereby condensed water may be dlscharged from the casing.

The gas-pipe is provided with a valve 23 of usual form, journaled in the bulged portion 24. Said gas-pipe is moreover provided with a small tube 25, which leads the gas in close proximity to the upper end of the burner, the gas discharged from said tube being permanently ignited, so that it will be sufficient to open the valve 23 for bringing the device into operation.

The igniting device is composed of a cock 26, a second cook 27 and a coupling nut 28, which secures the tube 25 to the cock 2.7. The mouth of the tube is provided with small openings 29 for the igniting flame and for the purpose of securing good burning of the same.

The modified form shown in Fig. 3 isdistinguished merely by the arrangement of a modified Bunsen burner, provided with a mouth-piece 30 for a flexible tube, whereby the device may be placed at any desired place.

In Figs. 4 and 5 I have illustrated a coiled water-heating tube 15, the admission and discharge openings 18 and 19 of which are arranged in front of each other; said tube has a plurality of horizontally arranged series of coils, so that water is brought from the bottom to the top and then discharged the advantage that water flows upwardly so that shortly after the ignition of the. gas

through the portion a of the coiled tube 15 and downwardly through the portion 6 of said tube, whereupon the water is brought into the portion a of the coiled tube, through which it flows again upwardly and then againdownwardlythrough the portion 11,

the hot water ng ally discharged through the opening 19. The extension 18 serves to admit water into the coiled tube.

The device operates as follows :If it is desired to heat water, the valve 23 is opened and the gas is ignited. At the same time the cock of the water supply-pipe is opened, so that water is admited into the coiled tube. Owing to the arrangement of the casing and the comparatively small cross-section of the coiled tube made of copper or other suitable metal, and owing to the great number of windings, the water will be heated instantly,

hot water may be taken from the device.

As already described, the device is pref erably provided with a continuously burning igniting flame so that the gas discharged from the burner needs not be ignited manually at each operation.. After the use, the

valve 23 is turned off, whereby the device is brought out of operation.

wall, the lower portion of the drum being supported on the bottom and fitting snugly against the vertical wall, a top for the drum,

the top extending between the vertical plane ofthe drum, sleeves interposed beyond the extended portion of the top. and the horizontal'flange of the bottom, bolts extending through the top, the horizontal flange and the sleeves to lock the casing together, a series of. vertically disposed coils in the- .drum, the coils being spaced apart to form a central vertical passage, water inlet and outlet pipes connected with the coils, a burner in the bottom of the casing in alinement with the central vertical passage between the coils, and means for controlling theburner.

In testimony whereof I have hereunto set :my handin presence of two witnesses.
